The AR7701-S Bolt-Down Kit is to be used for IBC High Seismic Area compliant installations.
The AR7701 and Pallet Bracket may be used for installations in IBC Low Seismic Area and IBC Moderate Seismic Area. The AR7701 is painted black to match the cabinet. The pallet bracket is metallic.
Note: the pallet bracket and AR7701 Bolt-Down Kit in the illustrations below are installed both inside and outside of the cabinet. They only need to mount inside or outside the cabinet, not both.
The AR7700 is for stabilization and does not bolt to the floor. It is not a seismic mounting bracket.

Bolt hole dimensions for AR3100 using the pallet bracket and AR7701 are in the file below "BSYN-6MX6P7_R6_EN".
Bolt hole dimensions for the AR7701-S are in the file below "IBC High Seismic Area Bracket Bolt Hole Dimensions".
Bolt hole dimensions for other cabinets can be found on each individual cabinet's product page of the APC website under the Documentation tab.
